CATTLE-STANCHION.

Specification of Letters Patent.

Patented Aug. 8, 1905.

Application filed June 22, 1904. Serial No 213,594..

To etZZ- whom, it may concern:

Be it known that I, CHARLES W. MAYER, of Rochester, in the county of Monroe and State of New York, have invented a certain new and usefulCattle-Stanchion, of which the following is a specification.

My invention has for its object the production of a cattle-stanchion which is particularly simple and cheap in construction ing-frame therefor being also shown. Fig. 2 is a top plan of the stanchion. Fig. 3 is an edge view of an upper part thereof. Fig. 4

is an edge view of contiguous portions of the movable upright bar and the part to which the same is pivoted. Fig. 5 is a detail view of the locking member and a portion of its supporting-chain. Fig. 6 is a sectional view on line A A, Fig. 1, the lower end of the movable upright bar being shown by dotted lines.

My stanchion comprises opposite upright bars 1 and 2, one of which, as 2, is movable relatively to the other, and a locking member 3 for preventing the relative movement of the bar 2.

The bars 1 2 are preferably formed U- shaped in cross-section, the grooves thereof opening outwardly, and one of said bars, as 1, is provided at its upper and lower ends with lateral extensions 4 5, the lower one, 5, terminating in a vertically-extending part 6, having lengthwise front and rear engaging surfaces 7 8, spaced apart a less distance, Fig. 4, than the front and rear surfaces of the main portion of the bar 1. The upper lateral extension 4 is formed with a socket 9, which is provided with upright inner, front, and rear engaging surfaces 10 11 12 and is formed by removing the lower wall of the groove made by the U-shaped formation of the bar 1.

The upright bar 2 is pivoted at 13 intermediate of its length to the upper end of the upwardlyextending part or post 6, and the opposite ends of said bar are provided with upright surfaces which normally engage the surfaces 7 8 1O 11 12 and, together with the locking member 3, hold the bar 2 firmly and positively in its upright or operative position with its upper end in the socket 9. When the bar 2 is moved into its inoperative position (indicated by dotted lines, Fig. 1) to permit an animals head to be placed in or removed from the stanchion, a face 14 on the lower end of said bar engages the bar 1 be,

neath the pivot 13 and limits the movement of said bar 2. In the preferable construction of my cattle-stanchion the face 14 is formed at the inner end of a cut-out in the lower end of the bar 2, and the side walls of said cutout engage front and rear surfaces of the bar 1 when the bar 2 is in its inoperative position, and thus prevent lateral displacement of the lower end of said bar 2. By constructing and pivoting the bars 1 2 as described a particularly cheap and durable structure is provided in which the strain on the connecting-pivot for the bars and the liability of the undue detachment of said bars is reduced to a minimum.

The locking member 3 for preventing the movement of the bar 2 relatively to the bar 1 is held in its operative or normal position by the weight of the stanchion, being here shown as pivoted at 15 intermediate of its length to the upper lateral extension 4 of the bar 1 and as having one end pivotally connected to a supporting-chain 16 and its other end formed with a cut-out 17 and a cam-face 18, leading to said cut-out.

I generally arrange the member 3 within the groove made by the U-shaped formation of the upper lateral extension 4 and utilize the side walls of said groove to prevent acci dental lateral displacement of the member 3. The supporting-chain 16 is connected to any suitable frame 19, which may also be connected by a chain 20 to the lower lateral eX tension of the bar 1. i

As the bar 2 is moved into operative position its upper end engages the cam-face 18 of the locking member 3 and moves the end of the member 3 provided with said face upwardly against the influence of the weight of the stanchion until an edge of the upper end of the bar 2 registers with the cut-out 17, whereupon the weight of the stanchion moves the locking member into operative position. To those skilled in the art it will be understood that by utilizing the weight of the stanchion to hold the member 3 in its operative position a particularly strong lock is provided and that the liability of the and efficient accidental unlocking of the bar 2 is reduced to a minimum.

The construction and operation of my stanchion will now be readily understood upon reference to the foregoing description and the accompanying drawings, and it will be noted that more or less change may be made in the component parts thereof without departing from the spirit of my invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A cattle-stanchion comprising opposite bars, one being movable relatively to the other, and a lock for preventing said bar from such relative movement, the lock being held in operative positionv bythe weight of the stanchion, substantially as and for the purpose described.

2. A cattle-stanchion comprising opposite bars, one being movable relatively to the other, and a locking member for preventing said bar from such relative movement, one of said bars being supported on the locking member for holding said member in operative position, substantially as and for the purpose specified.

3. A cattle stanchion comprising opposite bars, one being carried by the other and movable relatively thereto, and a locking member for preventing said bar from such relative movement, the other of said bars being supported on the locking member for holding said member in operative position, substantially as and for the purpose specified.

4. A cattle-stanchion comprising a support, opposite bars, one being carried by the other and movable relatively thereto, and a locking member for preventing said bar from such relative movement, the locking member being connected to the support, and the other of said bars being supported on the locking member for holding said member in o erative position, substantially as and for t e purpose set forth.

5. A cattle-stanchion comprising a support, opposite bars, one being carried by the other and movable relatively thereto, and a locking member forpreventing said bar from such relative movement, the looking member being pivotally connected to the support, and the otherof said bars being pivotally supported on the locking memberfor holding said member in operative position, substantially as and for the purpose described.

6. A cattle-stanchion comprising a support, opposite bars, one being movable relatively to the other, and a locking member having one end pivotally connected to the support, and its other end cooperating with the relatively movable bar, the other of said bars being pivotally connected to the locking member intermediate of its ends, substantially as and for the purpose specified.

7. A cattle-stanchion comprising opposite bars, one being pivoted intermediate of its ends and having one of its ends movable into engagement with the other barfor limiting the movement of the pivoted bar, substantially as and for the purpose set forth.

8. A cattle-stanchion comprising opposite bars, one being pivoted intermediate of its ends to the other of said bars and having one of its ends movable into engagement with the other bar for limiting the movement of the pivoted bar, and a locking member for preventing the pivoted bar from movement on its pivot, the other of said bars being supported on the locking member for holding said member in operative position, substantially as and for the purpose described.

9. A cattle-stanchion comprising a bar having its lower end provided with a lateral extension terminating in a vertically-extending' part, and a bar pivoted intermediate of its ends to the vertically-extending part and having one of its ends movable into engagement with the first-mentioned bar for limiting the movement of the pivoted bar, substantially as and for the purpose described.

11. A cattle-stanchion comprising opposite bars, one having inner, front and rear engaging surfaces, and the other bar being pivoted intermediate of its ends and having one of its ends provided with means for engaging the former surfaces at a point beneath the pivot for the pivoted bar, substantially as and for the purpose set forth.

12.
